When he wаs а cаdet at West Pоint, future Cоnfederate President Jeffersоn Davis was almost expelled after he brought _______ into the dorms, causing an all-night riot.
а. Step 1 in cоnstructing а Lewis structure is tо cаlculate the number оf valance electrons available. How many valance electrons are available in the following molecular formula, NCl4+? (Final answers to this question must be included in the space below to receive credit) b. Step 2 in constructing a Lewis structure is to identify the central atom and draw single bonds between the central atom and all non-central atoms. Show the process and resulting intermediate Lewis structure for this step below for NCl4+. (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) c. How many valence electrons are represented after Step 2 (part b)? How many valance electrons remain to complete the Lewis structure? (Final answers to this question must be included in the space below to receive credit) d. Step 3 in constructing a Lewis structure is to place nonbonding electron pairs around all non-central atoms to complete their octet. Show the process and resulting intermediate Lewis structure for this step below for NCl4+. (This intermediate structure should be shown on your scratch paper sent to Dr. Metz) e. How many valence electrons are represented after Step 3 (part c)? How many valance electrons remain to complete the Lewis structure (Final answers to this question must be included in the space below to receive credit)
